Description of the invention: [Technical field to which the invention pertains] The present invention relates to an in-mold decoration method, in particular to a type of plastic and a printed lion copy, respectively, for the production of a thin wire surface [previous technique] ❹ , With the development and advancement of manufacturing technology, new-generation electronic products, in addition to speaking/better execution and more user-friendly operation interface, are also designed to be new in order to shape their products. Features and styles, transforming consumers' impressions of this kind of electronic products, and gaining consumers' favor and increasing market share through the multiple characteristics and charm of the appearance design. Under this trend, ln Mold Decoration (IMD) has become a surface decoration technology widely used in related industries. In-mold decoration technology is the use of a moldable film for in-mold decoration, which can be used to replace the process of painting, printing, hot stamping and chrome in the traditional process, which can not only increase the surface effect and pattern of the product. And can significantly reduce the steps required for the finished product, in addition to shortening the time of the product process, but also significantly reducing costs. Therefore, it is widely used in mobile phones, notebook computers, and home appliances such as washing machines, and even in automotive instrumentation and housing decoration. Please refer to Figure 1, which shows the finished product manufactured by the current in-mold decoration technology. The main manufacturing steps are first printing ink onto the surface of the film substrate to form the desired copy 14 and printing 201014659 16 and the adhesive layer 17 on the surface of the copy 14. Finally, a process of injection molding is formed on the surface of the adhesive layer 17 to form a plastic 18 on the surface of the adhesive layer 17. It is noted that in order to prevent the injected plastic 18 from damaging the document 14 of the film substrate, that is, the 防α of the ink-repellent layer which is often repeated in the art, although the ink of the field 14 is effectively prevented from being ejected,拙18 she's also greatly increased the time and cost of production. In addition, if the red color produced by the fine mold is in a three-dimensional shape, a hot pressing process is performed before the injection molding is performed, and the film substrate is heated and molded. Money, if the film substrate used has been surface hardened, the surface (4) phenomenon is easy to occur during the process of seam forming, resulting in the finished product made by the flip decoration technology, the height of the three-dimensional forming and the R limb view. , can meet the requirements of product industry designers. SUMMARY OF THE INVENTION The present invention provides an in-plane decorating method, which mainly includes the following steps. First, a film substrate is provided having a first surface and a second surface relative to the first surface. The film was then printed on the first surface of the film substrate. Subsequently, a coating-hardening coating is applied to the copy and the hardened coating on the first surface is tempered to harden it. Then, the film substrate is subjected to a rolling type process, and the film substrate is subjected to an injection molding process to be formed on the second surface of the film substrate. In an embodiment, when the in-mold decoration method of the present invention is applied to a finished product of a 3D three-dimensional shape, a step of coating the hardened coating layer between the steps of hardening the coating of the 201014659 layer includes further performing a hot pressing. The procedure is to make the thin substrate and have a three-dimensional shape. Wherein, before the hot pressing process, the hot air drying treatment after applying the hard coating on the first & surface is performed to preliminarily dry the hardened coating [embodiment] Please refer to FIG. 2a-2d, this part of the drawing The related process of the in-mold decoration method provided in accordance with the present invention is shown. First, as shown in Fig. 2a, a film substrate 20 having a first surface 2A and a first surface 20b with respect to the first surface 20a is provided. In one embodiment, the film substrate is a transparent film and is received in a roll. Next, as shown in Fig. 2b, a roll-type printing press is used to form a pattern 22 on the first surface 2A of the film substrate 2A. Further, the step of printing the copy 22 on the first surface 2〇a of the film substrate 20 is carried out in a roll to ro® manner. That is, after the completion of the printing of the document 22, the film substrate 2 is still stored in the form of a roll. In the embodiment, in order to prevent the injection molding process in the back end process from causing the ink to be damaged by the ink copying, it is also considered that before the step of forming the copy & on the first surface 22a of the film substrate 20, First, the ink-repellent layer 21 is formed on the first surface pool of the film substrate 2Q by selective printing, and the upper surface of the ink-repellent layer 21 is formed by printing. The step of forming the ink-repellent layer 21 is also performed by means of a squeaking brush. In addition, since the thin-film substrate 20 after the printing of the copy 22 is stored in the form of a roll, "in order to prevent the copy 22 of the film substrate 2 from being contaminated or contaminated" on the printed substrate 22 on the film substrate 20 After the step, the protective film may be selectively attached to the first surface of the film substrate 2 () to cover the 201014659 cover file 22, and then the film substrate 20 is wound. Here, the step of attaching the protective film can be carried out by a backing machine. Subsequently, as shown in Fig. 2c, a hard coat layer 24 is applied to the surface of the text 22 and the hard coat layer 24 is irradiated with UV light to harden it. Wherein, the procedure for applying the hard coating layer 24 is to apply a hard coating layer 24 on the automatic coating machine to perform the hot air drying treatment after coating on the text 22 to preliminarily dry the hardened coating layer. The UV light irradiation hardens the hardened coating 24. Of course, if the film substrate 20 has been attached with a protective film after forming the copy 22, the protective film needs to be peeled off before applying the hardener 24 on the copy 22. Further, after the step of applying the hard coat layer 24, in order to prevent the hard coat layer 24 from being contaminated, a protective film may be attached to the first surface 2a of the film substrate 20. Next, as shown in FIG. 2d, the film substrate 20 is subjected to a rolling type process, and the film substrate 20 is subjected to die cutting by a steel knife rolling machine to cut a part of the film substrate 2 required. Hey. Subsequently, the film substrate 20 is subjected to an injection molding process through an injection molding machine to form a plastic 26 on the second surface 20b of the film substrate 2''. Since the injected plastic 26 is formed on the second surface 2Qb of the film substrate 2', the phenomenon of ink generation on the copy 22 on the first surface 2Qa is not caused. Specifically, if the 3D solid shape finished product is to be produced by applying the in-mold decoration technique of the present invention, the step of applying the hard coat layer 24 and the step of irradiating the hard coat layer 24 with uv light are used. In the meantime, another hot pressing procedure is performed to make the film substrate 2〇 have a three-dimensional shape. Referring to Figures 3a-3d', this portion of the illustration shows a related process for producing a three-dimensional finished product using the in-mold decoration method of the present invention. As shown in FIG. 3a, after the selective printing ink-repellent layer 21, the copy 22, and the uv hard coating 24 are sequentially formed on the first surface 20a of the film substrate 20, hot pressing may be performed. The hardened coating 24 is preliminarily dried before the procedure. After the hot air drying process is completed, the hardened coating 24 has been initially dried to aid in the formation of the film substrate 20 thereafter. Next, as shown in Fig. 3b, a first surface 2〇a of the film substrate 2 is heat-pressed using a hot press table together with a hot press mold to produce a desired three-dimensional shape of the film substrate 20.
